Abstract

This paper adopts an innovative method through combining an autoregressive distributed lag model and a quantile regression to examine the long-run equilibrium and short-run causal relationship between the stock price of Taiwan and the NTD/USD exchange rate from January 1980 to December 2014. The results indicate that there is long-run level equilibrium relationship between the stock price of Taiwan and the NTD/USD exchange rates at lower distribution of stock prices, and at higher and lower distribution of exchange rates. The causality results show that there is unidirectional causality running from Taiwan stock price to the NTD/USD exchange rate at higher distribution of exchange rates. The result shows that there is evidence in favor of the portfolio hypothesis.
